lepton-7/Open-Plate-Spectrophotometer
An open-source project to build a 96-well spectrophotometer operating at 620nm. Designed from the ground-up focusing on robust electronic design.

The 2SCR502UBTL is a bipolar made by ROHM Semiconductor in a SC-70(SOT-323) package with 3 pins. -55℃~+150℃ 1 NPN 200 200mW 200nA 300mV 30V 360MHz 500mA 6V NPN SC-70(SOT-323) Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1B_2E_3C, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-323_SC-70, from KiCad's library), ready for a KiCad board. 128 are in stock at JLCPCB (part C509802). 1 open-source board in 1 repository on GitHub use it.
